hardness testing for ball mill balls pfbl

The hardness of grinding media ball how to choose balls

But for the productivity of the ball mill, the productivity increases with the increase of the hardness of the ball in a certain range, but when the hardness exceeds a certain range, the productivity of the mill decreases. When the hardness of grinding media ball is too high, there are two unfavorable reasons for grinding: 1. The grinding media Ball

Cast Grinding Steel Balls 911Metallurgist

The number of impacts in primary ball mills are far more frequent but have less magnitude than those experienced in SAG mills. The increased frequency is due to the Increase in charge volume (35 40% versus 5 10%), higher mill speeds, and the larger number of balls per unit charge weight. The lower impact forces are due to a combination of both smaller ball masses and lower drop heights

(Received: February 1, 2016; Accepted: November 4, 2016)

Secondary ball mill balls experience significant levels of abrasive and corrosive wear, with insignificant levels of impact wear due to the small 2.5 60 mm diameters. They experience 25 40% less wear than in primary grinding of the same ore. High chromium balls may be economical for high levels of corrosive wear, preventing pitting, as they experience 25 30% less wear than forged
